I'm trying to implement a local library (made for me) but when I try to execute the code the console throws this error:
PS C:\Users\dydie\Documents\Proyecto Sena> node src/index.js
node:internal/modules/cjs/loader:942
throw err;
^
Error: Cannot find module './back js/algorithms.js'

}
Node.js v18.0.0
seems that the error comes from this line:
const utilities = require("./back js/utilities.js");
ironically I before used the same code for other file and it was working (and still working)
what can I do? I tried to delete and install node_modules and it didn't work.
any idea? thanks for your atention
If back js/utilities.js wants to require algorithms.js and it's in the same folder as utilities.js, then it should require('./algorithms.js'), not require('./back js/algorithms.js') Because the path for a require is relative to the file that is executing the require command.
~/index.js would need require('./back js/algorithms.js') to directly require ~/back js/algorithms.js but
~/back js/utilities.js would only need require('./algorithms.js') to require ~/back js/algorithms.js
Note that if ~/back js/utilities.js wrote require('./back js/algorithms.js') then it would be looking for ~/back js/back js/utilities.js...which is likely not the intended path.
